To all whom it may concern Be it known that I, WILLIAM GoRDoN, a citizen of the United States, residing at Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain Improvements in Buffing-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures,

In the use of buffing machines for boots and shoes, it has heretofore been necessary for the operator to step into different positions in order to bring the boot or shoe from one buffing device to another. A great deal of time is lost in this way, and the constant changing of position is very tiring upon the operator.

The principal object of the present invention is to avoid these object-ions by bringing the bufling devices or the similar devices for trimming, beading, or otherwise operating upon the shoe, into such relation to each other that the-y are all within easy reach of the operator, so that he may perform the desired operations without the necessity of stepping from one device to another. The amount of work performed by a single operator may be thus considerably increased, and the compact arrangement of parts results in a marked saving in floor space. This object is attained according to this invention by arranging the rolls or like rotary devices for operating upon the shoe 7 with their axes at an angle to each other, so

that the operator by standing in the opening of the angle may present the shoe to all of the devices without stepping into different positions.

The desired object may be further accomplished bymounting additional devices above and below the aforesaid devices in such manner as to be within easy reach of the operator. By the above mentioned arrangement of devices, a greater number than formerly may be embodied in one machine, so that much less space is occupied,

In the accompanying drawings which illustrate a preferred embodiment of this invention,-Figure 1 is a front elevation of the machine with a portion of the frame broken away; Fig. 2 is a side elevation with a portion of the frame, and a flue broken away, and a portion in section to show the eccentric for reciprocating the rolls; Fig. 3 is an elevation of the opposite side; Fig. 4 is a top plan view.

In the specific construction shown, 1 designates the frame of the machine, which may be of any suitable shape, and which is provided with bearings near the lower end to support a main shaft 2 at the rear and a countershaft 3 at the front, from which shafts the operative parts of the machine are driven. The main shaft has fast and loose pulleys 4 and 5 at one end connected by a belt 6 with any suitable source of power. The main shaft has secured to it a pulley 7 connected by a belt 8 with a pulley 9 on the countershaft, by means of which the latter shaft is driven. V

The countershaft carries a second ulley 10 connected by a belt 11 with a pulley 12 on a shaft 13 mounted in bearings 14 and 15 on opposite sides of the machine. The bearing 14 is located farther to the rear than the bearing 15, so that the shaft 13 is inclined at an angle tothe front of the machine. The shaft 13 is provided with a finishing roll 16 having a covering of comparatively fine abrading material. The countershaft carries a third pulley 17 connected by a belt 18 with a pulley 19 on a shaft 20 mounted in bearings 21 and 22 on opposite sides of the machine. The bearing 21 is located farther to the rear than the bearing 22 so that the shaft 20 is inclined at the same angle to the front of the machine as the shaft 13. The shafts 13 and 20 are therefore arranged at an angle to each other. In order that these shafts may not interfere with each other, the bearings 14 and 15 are positioned slightly higher than the bearings-21 and 22. The shaft 20 carries a roughing roll 23 provided with a covering of abrasive material which is coarser than that on the roll 16. The pulley 12 is considerably smaller than the pulley 19 whereby the finishing roll is driven faster than the roughing roll, in order to polish the sole of the shoe better.

The countershaft carries a fourth pulley 24 connected by a belt 25 with a pulley 26 on a shaft 27 mounted in bearings 28 and 29 on the front of the frame. The shaft 27 is provided with a toplift roll 30 having a covering of abrading material su ciently coarse to abrade the nails when the toplift of the heel of a shoe is bufi'ed. The -end of the shaft 27 which is opposite the end having the pulley 26 is rovided with a device 31 which may be a s ank wheel, a brush or the like. The bearings 28 and 29 are somewhat lower than the bearings of the finishing and roughin rolls so that the vertical plane of thesha t 27 may intersect the vertical planesof .the shafts 13 and 20. The

three rolls 16, 23, and 30 therefore have their axes arranged in vertical intersecting planes, and at an angle to each other. The mainshaft 2. carries a pulley '32 connected by a belt 33 with a pulley 34 on a horizontal shaft 35 mounted in bearings 36 and 37 secured to the frame toward its rear. The shaft 35 has bevel gears 38 and 39 on its ends meshing with bevel gears 40 and 41 bell-crank levers 48 pivoted at 49.

securedto the lower ends of vertical shafts 42 and 43 mounted in lower bearings 44 and upper bearings 45.

The portions of the shafts 42 and 43 which fit in the upper bearings 45. are enlarged and carry at their upper ends eccentric studs 46 connected by links 47 to the rear end si e front ends of these levers are pivoted to I sleeves 50 secured to the shafts 13 and 20.

rotar The roughing and finishing rolls are thus given a reciprocating motion as well as a one. This combined motion results in a etter polishing of the soles of shoes during the bufling operation than can be obtained by a simple rotary motion of the rolls.

The main shaft 2 carries a large pulley 51 from which a belt 52 passes over idlers 53 to a pulley 54 on a vertical shaft 55, supported in bearings 56 and 57 on a bracket 58 located toward the front of the machine. The lower end of theshaft 55 carriesa bulfing pad 59 which is supported at a convenient distance above the roughing roll. The bufiing pad is covered with fine abrading materia and is driven at a high speed. It is used for the final polishing operation and may be of any preferred type, that known as the Naumkeag being preferred.

The main shaft carries a pulley 60 connected by a belt 61 with a pulley 62 on a shaft 63 mounted in bearings 64 near the rear of the machine. This shaft carries a blower 641 which rotates in a casing 65 secured to the rear of the frame. The casing has an outlet 66 extending from its ppri hbearings 14, 15, 21 and 22. From the lower side of the right-hand flue 67 extend two branch flues. 70 and 71 leading respectively to the top lift roll 30 and the shank wheel or similar device 31. The inlet end of the flue 71 is enlarged so as to partially inclose the..device 31 and the outside portion of this end is hinged as shown in Fig. 3 so as to permit access to this device for its removal and replacement by a similar device. From the upper side of the left-hand flue 67, a branch flue 72 extends, which is curved first to the right and then toward the front of the machine so as to bring its inlet end close to the buifing pad '59. This flue carries the bracket 58 and the bearin for the idlers 53. It will be seen that all the uffing devices are close to the inlet ends of flues which lead to the blower so that the abraded material is sucked into the flues and carried off. The inlet ends of the flues for the top lift roll, the roughing roll, and the finishing roll are preferably provided with hinged hoods which serve to direct the abraded material into the flues.

The operation of the machine has been fully set forth in connection with the detailed description and need not be repeated. While in the above description, a complete machine has been described in detail in order to fully set forth the preferred manner of applying the invention, it will be understood that various changes may be made in arrangement and details without departing from the spirit of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. A machine for buffing shoes having, in combination, a plurality of bufling rolls the axes of which are arranged at an angle to each other, the space beneath said rolls as well as that included in the angle between them being free and unobstructed whereby a shoe may readily be moved from contact with the under portion of one roll into contact with the under portion of the other, means for rotatin said rolls, and means for reciprocating sai rolls longitudinally of their axes.

2. A machine for bufiing shoes having, in combination, a buffing roll to which a shoe is to be manually presented, a second roll having its axis arranged at an angle to that of the first, the space beneath said rolls, as well as that included in the an le between them being free and clear where y a shoe may be moved directly from contact with the under portion of one roll into contact with the under portion of theother at will, and means for rotating said rolls.

3. A machine'of the class described having, in combination, a roughing roll and a finishing roll mounted at an angle to each other, the space included in the angle between said rolls being free and unobstructed whereby a shoe may be brought into operative relation with said rolls alternately at 5 will, means for rotating said roughing roll, and means for rotating said fimshing roll faster than said roughing roll.
